Scientific advisors

Dr Kaustuv Bhattacharya

Specialist Metabolic Paediatrician

Dr Kaustuv Bhattacharya is a paediatrician trained in the United Kingdom. His metabolic training was in London at Great Ormond Street Hospital for Children.

Having completed a fellowship in metabolic medicine and newborn screening in Sydney, he completed clinical research in glycogen storage diseases with the late Dr. Philip Lee and obtained a research MD in clinical nutrition for this work from the University of London. His work also led to a new carbohydrate therapy for glycogen storage disease being developed and marketed.

The Charles Dent Metabolic Unit, at The National Hospital for Neurology and Neurosurgery London is a large adult clinical metabolic service and Dr Bhattacharya was involved in the management of the 1500 adults in this clinic. He moved to Sydney, Australia in June 2008, where he is now practicing as a specialist paediatric metabolic physician.

He is continuing clinical research projects in several inborn errors of metabolism, allied to the NSW newborn screening programme and is the principal investigator for 2 clinical trials. He has published over 20 papers in peer-review journals and continues to collaborate widely with various centres across the world. In Australasia he is known for his inclusive approach to engagement with peers.

He is a committee member of the International Congress of Inborn Errors of metabolism scientific programme committee for Rio de Janeiro in 2017 and successfully led the bid for the same meeting to be hosted in Sydney in 2021, for which he will be chair of the local organising committee.

Dr Andrew Morris

Consultant Paediatrician

Dr Andrew Morris is a Consultant and Senior Lecturer in Paediatric Metabolic Medicine. He works on the Willink Metabolic Unit, which is part of Genomic Medicine in the Central Manchester University Hospitals. This unit has 6 consultant metabolic paediatricians and provides a service to the North of England through a clinical network.

Dr Morris has been a consultant since 1996 first in Newcastle-upon-Tyne and then at Great Ormond Street Hospital in London, before moving to Manchester in 2003. He has extensive experience of inborn errors of metabolism in children and some experience with adults. His research has primarily concerned the diagnosis and management of mitochondrial disorders and fatty acid oxidation defects. He has considerable experience of managing patients with classical homocystinuria and remethylation disorders.

He is on the Steering Group for E-HOD, the European Network and Registry for Homocysinurias and Methylation Defects; he is Leader of the Classical Homocystinuria Guidelines Group and the Work Group on Evaluation of the Project.

Professor Bridget Wilcken


Professor Bridget Wilcken has spent her professional life in the diagnosis and clinical care of individuals affected by metabolic disorders, and also has had extensive research interests in this area, in particular in homocystinuria.  She is internationally recognized both for her contributions to the inborn errors field and to newborn screening.
Her early research interests saw her focus on homocystinuria and the clinical features and diagnosis of this in Australia. She was prominent in the introduction of betaine as a treatment in pyridoxine-non-responsive cases of homocystinuria.  It is without a doubt that her research outcomes have resulted in an improvement in the quality of life of individuals affected by the disease.

Professor Wilcken is a founding member of the Australasian Society for Inborn Errors of Metabolism, contributed substantially to the founding and organisation of the International Society for Neonatal Screening, has served on committees of professional organisations, authored numerous publications and several book chapters and given invited presentations both on metabolic diseases and newborn screening worldwide.   She has a university appointment as Clinical Professor in the Discipline of Paediatrics, University of Sydney and was Clinical Director of the New South Wales Biochemical Genetics and Newborn Screening Services at the Children’s Hospital at Westmead.

She graduated in medicine from Edinburgh in 1956 and worked in Edinburgh and London before coming to Sydney, Australia.  She is former President of the Human Genetics Society of Australasia, the International Society for Neonatal Screening (ISNS), and the Australasian Society for Inborn Errors of Metabolism, and former chair of the Genetics Services Advisory Committee for New South Wales. In 2002 she was awarded the Order of Australia and in 2004 the Guthrie Medal of the ISNS for services to newborn screening.

Collaborating Partners


We are pleased to be collaborating with the following organisations:

The European Network and Registry for Homocystinurias and Methylation defects

The European Network and Registry for Homocystinurias and Methylation defects (E-HOD) is an international consortium of clinicians, scientists, dieticians, patient organisations and industry representatives with a focus on homocystinuria and (re)methylation defects.  It has three major activities:  Collecting longitudinal data into a registry; developing evidence-based consensus diagnostic and clinical care protocols; and evaluating different newborn screening programmes for HCU and producing a position paper.

HCU Network America

HCU Network America is a recognized US based 501(c)(3) non-profit organization dedicated to helping patients with Homocystinuria (HCU) and related disorders manage their disease and find a cure. We strive to create connections, provide educational resources, and drive research towards a cure!

Mission & Vision




This overarching vision statement informs the direction of HCU Network, inspiring and motivating all who are involved with its activities undertaken to unite the HCU community, achieve actual awareness, seeking improved treatment options and related outcomes, improved diagnostic methods and supporting and encouraging research for a cure.

Current Projects in brief

Project A:
Patient Identification Campaign & Homocystinuria Disease Patient Registry

Patient registries are crucial for finding cures for rare disease as populations are small and geographically dispersed. The purpose of the Homocystinuria Disease Patient Registry is to organise and quantify the Homocystinuria community.

The registry will serve two purposes.  At first instance, to unite the HCU community and provide a support network for affected individuals and families. A support network can alleviate some of the stress associated with both the diagnosis of HCU, and living with the disease. Secondly, the registry will provide the data to advance medical research for HCU and improve therapeutic development and quality of life for those living with HCU.

Project B:
HCU Community Research

To compile a survey for both patients and relevant health professionals to obtain a complete perspective on the current state of treatments, compliance and reasons for non compliance, and research into HCU.

It is anticipated that the survey results will support the proposed need for reform in the funding of treatment, diagnostic methods and research. The survey will be used specifically to identify issues within the current system and support any future funding submissions. It will also be used to guide our organisation as to how we can best support affected individuals and families.

Project C:
Smartphone App Development

We are working in collaboration with AccuGo for the development of an iPhone App to assist with the management and tracking of the low protein diet. AccuGo was initially designed to ease the day to day management of the PKU diet by providing a quick and easy was to track foods eaten.

AccuGo for HCU a service provided by HCU Network Australia will have the following features specifically for HCU management:

  • Protein and methionine mode of tracking;
  • Overview of day’s running total of protein/methionine at a glance;
  • Historical graph showing totals over the past month;
  • Automatic calculation of protein/methionine;
  • Includes preloaded and searchable USDA based food items;
  • Add own foods and values to the database;
  • Community food list;
  • Email daily food records by date range including a summary of average over the date range.

Project D:
Research Grants & Travel Fellowships

It is our aim to encourage and support research into the disease including the translation of this research into the the clinical setting with the ultimate goal of improving therapeutic treatments.

Funding will be provided by way of research grants for new research projects aimed at improving the health and wellbeing of individuals affected by HCU. Annual awards for travel will also be awarded by way of travel fellowships to enable health care professionals to gain further knowledge in the area of HCU.

These opportunities will be dictated by fundraising capabilities.

Project E:
YouTube “Question & Answer Time”

HCU Network Australia aims to launch a HCU Question & Answer Time on YouTube and also have these ‘interviews’ available to view on our website and distributed to newly diagnosed families. They are proposed to be a video series in which renowned metabolic specialists would answer the most commonly asked HCU questions in short videos.
